The object of inve'ntionis to improve theconstruction of locomotive axles and g This object I attainby. making. a, portion of a wheel an integral:

' the driving pinsi'separated therefrom;

Flg. 2 is anendview of the axle shown in Fig.1;

Fig.

driving wheel and: a portionof the axle;

.and

.tionfof the invention.

.As the power of a locomotive, as well as I the stroke,'has increased to such an extent.

that large driving pins and enlarged axles are now necessary, I have been enabled to [retain the necessary proportions between the parts by'making enlargementseon the ends of the axle which fit openings in'the wheel V locomotives, havinglntegral enlargements at} ,each end; anddriving pins mounted in the and which carry the driving pins.

1 is the axle liavin enlargements22 at each side. These enfiargementsare oblong in shape'as shown, and one enlargement in the present instance is at right angles to the other,xb'ut the angle may vary without departing'fro'm the essential features ofthe invention. These enla-rgements'are rounded at each end and are slightly tapered, fitting corresponding openings in the body of the wheel centre 3; a j

The wheel 3 is the ordinary type of driving wheel and has spokes 4, a tire 5, and a counterbalance 6. The wheel is driven onto the enlargements 22'? of the axle and is prevented from turningthereon by the shape of said enlargements, Y

' The driving pin 7 is driven intoan opening 8 in the enlargement 2 as clearly shown. in Fig. 3, so that the driving pin is connected directly to theiaxle In some instances an axle made in 3 isa sectional view through the befof the proper proportion to provide sufe ficlent strength for theiparts, without in any Fig. 4 is a view'illustrating modifica- V D axle, the lnvention is applicable to a crank- .axle of a three vlargements ateach end and having openings,

the projections may be circularinform, as 4 at 2 and 2, Fig. 4:, fitting circular openings inth bodyiofthe wheel. '.In .this case a key or other means offastening the parts be used tosecurelyattachthe wheel to the axle after it has been driven into posi tion. 1 7 I By making the enlargements 2.-2 anintegral part ot the axle and driving thejpin' H1150 an openlng in these enlargements, the

pin is directly connected to the axle and can wayinterferingwith the size ofthe axle.

While the drawing shows a plain driving or four cylinder locomotive. I claim: i i 1; The combination of .a driving axle having an integral enlargement at one end; a

driving pin mountedin the enlargement;

and a wheel mounted on theenlargement'.

2. The-combination of'a-driving axle for enlargements. v

3. The combination of a driving axle having enlargements at eachend, said enlargements being at "an angle in respectto each other, and having'openings for driving pins; driving pins "driven into the openings; and driving wheels mounte'd 'on the enlargements. r v V 4." The combination of an axle having en-, I
